74ABT374CSC

Flip Flops Overview

The Fairchild Semiconductor 74ABT374CSC is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-STATE outputs designed for bus-oriented applications. It operates within a supply voltage range of 4.5V to 5.5V, with a typical propagation delay of 5ns at 5V with 50pF load. The device provides an output sink capability of 64mA and a source capability of 32mA. It utilizes a buffered positive edge-triggered clock and a common Output Enable (OE) signal across all flip-flops.

Flip Flops Feature Summary

Flip Flops Applications

• Bus-oriented data storage systems
• Memory address drivers
• Clock distribution networks
• General-purpose octal register configurations

Flip Flops Procurement Notes

Verify the specific manufacturer origin, as this component was originally produced by Fairchild Semiconductor, which has undergone corporate restructuring. Confirm that the received unit matches the original Fairchild specifications rather than subsequent onsemi iterations if strict legacy compliance is required. Check datasheet revisions for any subtle parameter shifts between manufacturing eras.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with high-drive 3-STATE outputs is required for bus architectures. Ensure the application supports the ABT logic family voltage levels and speed characteristics. Consider pinout compatibility with existing PCB layouts designed for standard 20-lead SOIC packages before finalizing the design choice.

Flip Flops Part Context

The 74ABT374 belongs to the ABT logic series, known for high-speed performance and strong drive capabilities compared to standard TTL or CMOS families. The 'CSC' suffix specifically denotes the 20-Lead Small Outline Integrated Circuit (SOIC) package variant manufactured by Fairchild Semiconductor. This part serves as a foundational building block for parallel data handling in digital systems.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74ABT374ADW from Texas Instruments and CY74FCT374ATSOC from Texas Instruments. Verify electrical parameters and pinout compatibility before substitution.
